Help - Using Laptop as Wireless Adaptor for 360

So I’ve been trying to use my laptop as a wireless adaptor for XBL. It works, but is incredibly laggy, is there any way I can increase performance, or is lagginess simply a draw back to using it this way? I was playing SFIV and in one particular match I had yellow (four bars) yet it still stuttered. Any help is appreciated…

So your using your laptop as a wireless bridge?

Basically, plugging the ethernet into my laptop, and using it’s wireless card to connect to my router…
